When working, the half shaft gear is sleeved into the small end of the expansion sleeve assembly, the radial expansion of the expansion sleeve assembly is driven by the axial movement of the conical spindle to fix the half shaft gear, and the working end of the indicating part abuts against the gear ring and rotates with the gear to obtain the gear ring runout detection data.

Description

Technical Field

[0001] This invention belongs to the technical field of gear testing equipment, specifically relating to a device for detecting radial runout of a differential half-shaft gear ring. Background Technology

[0002] The differential half-shaft gear is a core component of the automotive transmission system, and its radial runout accuracy directly affects the transmission smoothness, noise, and service life of the differential. Currently, the industry commonly uses a runout meter in conjunction with a mandrel to detect gear runout. However, this existing technology has the following main drawbacks: Low detection accuracy: Traditional clearance-fit mandrels have a clearance, resulting in large detection wobbling errors; rigid positioning flanges are forced to be flush with the gear end face, and when there is a perpendicularity error between the gear reference end face and the inner hole, it will force the gear inner hole to produce elastic bending, introducing false runout.

[0003] Low clamping efficiency: Existing testing devices require manual alignment of the gear grooves for circumferential positioning, and one mandrel can only be used for gears of one inner diameter. When testing gears of different specifications, the mandrel needs to be changed frequently, which seriously affects the efficiency of batch testing.

[0004] Poor versatility: Existing devices are mostly specially designed and can only be adapted to specific models of half-shaft gears. The tooling cost is high and cannot meet the production needs of multiple varieties and small batches. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned deficiencies of the prior art and provide a half-shaft gear ring inspection device with high detection accuracy, high clamping efficiency, controllable tension force, and strong versatility. This device can effectively eliminate the influence of end-face perpendicularity error on the measurement results, achieving high-precision batch inspection of half-shaft gears. To achieve the above-mentioned objective, the technical solution adopted by this invention is as follows: The half-shaft gear ring detection device includes an indicator component, a push and positioning component, an expansion sleeve assembly, a tapered spindle, and a clamping cone assembly; The expansion sleeve assembly, the tapered spindle, and the clamping cone assembly are arranged horizontally and coaxially. The tapered spindle is rotatably mounted on the spindle support, and the expansion sleeve assembly is rotatably mounted on the expansion sleeve support; the spindle support, the expansion sleeve support, and the clamping cone assembly are slidably mounted on the base. The display component is vertically disposed at the top gap of the expansion sleeve assembly; The half-shaft gear is fitted into the small end of the expansion sleeve assembly. As the small end of the tapered spindle is inserted into the small end of the expansion sleeve assembly, the expansion sleeve assembly radially expands and tightens to fix the half-shaft gear. The working end of the display component abuts against the half-shaft gear and reads the value as it rotates.

[0006] Furthermore, the pushing and positioning component includes a support cylinder, a fixed ring disk, and a floating ring disk; The support cylinder is detachably provided on the large end of the tapered spindle, with the open end of the support cylinder facing the small end of the tapered spindle; A connecting cylinder is slidably provided inside the support cylinder. The fixed ring is fixed at one end of the connecting cylinder located outside the support cylinder, and a push spring is connected to the other end. The push spring is located between the support cylinder and the inner wall of the support cylinder. The fixed ring disk and the floating ring disk are respectively provided with a matching spherical recess and a spherical protrusion on their respective sides that are close to each other, and the spherical recess and the spherical protrusion are slidably engaged; The fixed ring disk and the floating ring disk are provided with a plurality of return springs evenly spaced along the circumference on the side that are close to each other. The support cylinder has a limiting piece at its open end to prevent the connecting cylinder from popping out.

[0007] Furthermore, the expansion sleeve assembly includes a tapered expansion sleeve; The outer wall of the large end of the conical expansion sleeve is provided with several limiting grooves along the circumference, and a sliding block is slidably provided in the limiting groove; a limiting ring is provided at the opening end of the limiting groove to limit the sliding block from popping out, and an arc-shaped limiting block is fixedly provided on the side of the sliding block facing the opening end of the limiting groove. The small end of the tapered expansion sleeve faces the main shaft support seat; The expansion sleeve support includes a vertical plate, which is rotatably connected to the large end of the tapered expansion sleeve and has a coaxial opening adapted to its inner hole.

[0008] Furthermore, the expansion sleeve support also includes a flat plate, a drive throttle, and drive teeth; The vertical plate is provided on the top of the flat plate; The top of the base is provided with a rack along the movement direction of the expansion sleeve support; The bottom of the plate is provided with a strip groove along the direction of movement, and the drive teeth are rotatably provided in the strip groove. The drive handle is rotatably provided on the outer wall of the plate. The drive handle is coaxially and fixedly connected to the drive teeth, and the drive teeth mesh with the rack.

[0009] Furthermore, the expansion sleeve support also includes a clamp, and the base is provided with a slide rail; The clamp is detachably provided on the side wall of the plate, and the clamp is connected to the slide rail to restrict the sliding of the expansion sleeve support.

[0010] Furthermore, the clamping cone assembly includes a clamping cone head and a clamping cone seat; The clamping cone is fixedly provided on the clamping cone seat, and a positioning recess is provided at the center of the small end face of the tapered spindle. The clamping cone is coaxial with the tapered spindle and rotatably connected to it, and its cone tip is adapted to the positioning recess.

[0011] Furthermore, a throttle handle for rotating the tapered spindle is fixedly provided on the large end face of the tapered spindle.

[0012] Furthermore, the clamping cone assembly and the spindle support are respectively connected to the first drive cylinder and the second drive cylinder on the opposite sides.

[0013] Furthermore, the indicator component includes a support shaft, a positioning plate, a dial indicator, a connecting cylinder, a return spring, a limiting ring block, and a steel ball; The positioning plate and the limiting ring block are fixedly provided on the support shaft from top to bottom; The connecting cylinder is sleeved on the support shaft, and the connecting cylinder is located between the positioning plate and the limiting annular block; The reset spring is provided between the bottom of the connecting cylinder and the top of the limiting annular block; The dial indicator is detachably mounted on the outer wall of the connecting cylinder, and the working end of the dial indicator is connected to the positioning plate. The connecting cylinder is fixed to the base by an external fixing bracket.

[0014] The present invention has the following beneficial effects: Significantly improved detection accuracy: By pushing the spherical floating structure in the positioning component, adaptive fitting of the gear end face is achieved, completely eliminating false runout caused by end face perpendicularity error and meeting the gear detection requirements; the clearanceless fit between the tapered expansion sleeve and the tapered spindle eliminates the wobble error of the traditional mandrel.

[0015] Significantly improved clamping efficiency: By adopting the automatic pre-tightening of the push spring and the axial movement and expansion of the tapered spindle, a one-click operation of "fitting-tightening-inspection" is realized, eliminating the need to adjust the axial positioning dimensions and improving the inspection efficiency for a single person.

[0016] High versatility: By replacing the tapered expansion sleeve and arc-shaped limit block of different specifications, it can cover most differential half shaft gears, reducing tooling costs; the expansion sleeve support can slide along the slide rail to adjust its position and adapt to inspection workpieces of different lengths.

[0017] Simple and reliable operation: The drive throttle and rack mechanism enable precise movement of the expansion sleeve support, and the clamping device quickly locks the position; the display component adopts steel ball contact measurement, which has low wear, long service life, and is easy to calibrate and maintain.

[0022] The base 8 is a cuboid structure, with a slide rail 801 and a rack 405 parallel to each other along its length on the top. The spindle support 9, the expansion sleeve support 4, and the clamping cone assembly 6 are slidably mounted on the slide rail 801 from left to right, and their sliding directions are parallel to the slide rail 801. A second drive cylinder 10 is connected to the left side of the spindle support 9, and a first drive cylinder 7 is connected to the right side of the clamping cone assembly 6. Both drive cylinders are servo cylinders, and pressure sensors are installed at their output ends (the drive cylinder stops operating after a predetermined pressure value is reached), which can precisely control the thrust and stroke.

[0023] The tapered spindle 5 is horizontally mounted on top of the spindle support 9 and is supported by precision bearings, allowing it to rotate freely around its own axis. A throttle handle 11 is fixedly mounted on the left (larger) end of the tapered spindle 5 for manual rotation; a 60° positioning recess is machined at the center of the right (smaller) end face to fit the clamping cone head 601 of the clamping cone assembly 6. The tapered section of the tapered spindle 5 has a taper of 1:15 and its surface is ground.

[0024] The expansion sleeve assembly 3 is horizontally mounted on top of the expansion sleeve support 4 and is coaxially arranged with the tapered spindle 5. The small end of the expansion sleeve assembly 3 faces the tapered spindle 5, and the large end faces the clamping cone assembly 6. The display component 1 is mounted directly above the expansion sleeve assembly 3 via a fixed bracket, and its working end abuts vertically downward against the top surface of the gear ring of the half-shaft gear 12.

[0025] The positioning component 2 is installed at the large end of the tapered spindle 5 to achieve axial pre-positioning and end-face adaptive fitting of the half-shaft gear 12. For example... Figure 4 As shown, the push positioning component 2 includes a support cylinder 201, a push spring 202, a connecting cylinder 203, a fixed ring disk 204, a spherical recess 205, a spherical protrusion 206, a return spring 207, and a floating ring disk 208.

[0026] The support cylinder 201 is a cylindrical structure with an open left end and a closed right end, and is detachably connected to the outer wall of the large end of the tapered spindle 5 via threads. The connecting cylinder 203 is slidably installed inside the support cylinder 201, with its left end extending out of the open end of the support cylinder 201 and welded to the left end face of the fixing ring 204. The push spring 202 is disposed inside the support cylinder 201, with its right end abutting against the inner wall of the support cylinder 201 and its left end abutting against the left end face of the connecting cylinder 203, providing a leftward preload force to the connecting cylinder 203. A limiting piece is fixedly provided on the inner wall of the open end of the support cylinder 201 to limit the ejection of the connecting cylinder 203.

[0027] The fixed ring disk 204 has a spherical recess 205 machined at the center of its end face, and the floating ring disk 208 has a spherical protrusion 206 machined at the center of its end face to match the spherical recess 205. The two form a spherical sliding pair, which can realize angular swing. The surface of the spherical pair is ground, with a contact area ≥85% and a roundness tolerance ≤0.002mm. Four return springs 207 are evenly spaced circumferentially between the fixed ring disk 204 and the floating ring disk 208. The two ends of each return spring 207 are hooked onto the lugs of the fixed ring disk 204 and the floating ring disk 208, respectively, so that the floating ring disk 208 automatically returns to the center when there is no external force.

[0028] The expansion sleeve assembly 3 is used to achieve radial expansion and tightening fixation of the half-shaft gear 12. For example... Figure 4 As shown, the expansion sleeve assembly 3 includes a conical expansion sleeve 301, a limiting groove 302, a compression spring 303, an arc-shaped limiting block 304, a sliding block 305, and a limiting ring 306.

[0029] The tapered expansion sleeve 301 is an integral open tapered sleeve, made of 65Mn spring steel in this embodiment, with a quenching hardness of HRC38-42. In its free state, the outer diameter of the small end is 22.4 mm, the outer diameter of the large end is 25 mm, and the wall thickness is 2 mm. It has three axial openings evenly spaced along the generatrix direction, each 1 mm wide. The small end of the tapered expansion sleeve 301 faces the tapered spindle 5, while the large end is rotatably mounted on the vertical plate 401 of the expansion sleeve support 4 via a precision bearing. The tapered expansion sleeve 301 can be customized to different specifications to meet specific gear inner diameter requirements.

[0030] Three limiting grooves 302 are evenly distributed along the circumferential direction and the generatrix direction of the tapered expansion sleeve 301 on the outer wall of the large end (i.e., three are provided along the generatrix direction for each segment; this is only one embodiment, but several limiting grooves 302 can also be provided along the generatrix for a certain segment). A sliding block 305 is slidably installed in each limiting groove 302. A compression spring 303 is provided between the sliding block 305 and the bottom of the limiting groove 302 to provide outward preload for the sliding block 305. An arc-shaped limiting block 304 is fixedly provided on the outer end face of the sliding block 305. The inner arc surface of the arc-shaped limiting block 304 is adapted to the end face of the half-shaft gear 12, and the arc direction is as follows: Figure 5 It can be locked inside the spline of the half-shaft gear 12 to restrict its rotation and form a positioning effect. A limiting ring 306 is fixedly provided at the open end of the limiting groove 302 to restrict the sliding block 305 from popping out.

[0031] The expansion sleeve support 4 supports the expansion sleeve assembly 3 and can slide along the slide rail 801 to adjust its position. Figure 3 As shown, the expansion sleeve support 4 includes a vertical plate 401, a flat plate 402, a drive throttle 403, a drive tooth 404, a rack 405, a strip groove 406, and a clamp.

[0032] The flat plate 402 is set horizontally, and its bottom is slidably connected to the slide rail 801 via a slider. The vertical plate 401 is vertically welded to the top right end of the flat plate 402. The large end of the tapered expansion sleeve 301 is mounted on the vertical plate 401 via a precision bearing. The vertical plate 401 has an opening with a diameter of 26mm that is coaxial with the inner hole of the tapered expansion sleeve 301, allowing the tapered spindle 5 to pass through.

[0033] A strip-shaped groove 406 is formed along the length of the bottom of the plate 402. A drive tooth 404 is rotatably mounted in the strip-shaped groove 406, and the drive tooth 404 meshes with a rack 405 on the top of the base 8. A drive handle 403 is rotatably mounted on the front side wall of the plate 402, and the drive handle 403 is coaxially and fixedly connected to the drive tooth 404. Rotating the drive handle 403 causes the drive tooth 404 to roll along the rack 405, thereby driving the expansion sleeve support 4 to move along the slide rail 801. A clamp is detachably mounted on the left side wall of the plate 402. When the clamp clamps the slide rail 801, it can lock the position of the expansion sleeve support 4.

[0034] The clamping cone assembly 6 supports the right end of the tapered spindle 5 and provides axial thrust. For example... Figure 1 As shown, the clamping cone assembly 6 includes a clamping cone head 601 and a clamping cone seat 602. The clamping cone seat 602 is slidably mounted on the slide rail 801, and its left side is connected to the piston rod of the first drive cylinder 7. The clamping cone head 601 is fixedly mounted on the center of the left side wall of the clamping cone seat 602, coaxially arranged with the conical main shaft 5, and its cone tip is 60°, which is adapted to the positioning recess at the right end of the conical main shaft 5.

[0035] The indicator unit 1 is used to measure the radial runout of the gear ring of the half-shaft gear 12. For example... Figure 2 As shown, the display component 1 includes a support shaft 101, a positioning plate 102, a dial indicator 103, a connecting cylinder 104, a return spring 105, a limiting ring block 106, and a steel ball 107.

[0036] The support shaft 101 is vertically mounted, and its top is connected to the base 8 via a fixed bracket. A positioning plate 102 and a limiting annular block 106 are fixedly mounted on the support shaft 101 from top to bottom. A connecting cylinder 104 is slidably sleeved on the support shaft 101, located between the positioning plate 102 and the limiting annular block 106. A return spring 105 is sleeved on the support shaft 101, located between the bottom of the connecting cylinder 104 and the top of the limiting annular block 106, providing a downward preload to the support shaft 101.

[0037] A dial indicator 103 is detachably mounted on the right side wall of the connecting cylinder 104 via a clamp. The dial indicator 103 has a graduation of 0.001 mm, and its measuring rod points vertically upward, with its top end abutting against the bottom surface of the positioning plate 102. A GCr15 steel ball 107 with a diameter of 5 mm and an accuracy class of G10 is embedded in the center of the bottom of the connecting cylinder 104. During operation, the ball abuts against the top surface of the gear ring of the half-shaft gear 12.

[0038] Workflow: According to the specifications of the half-shaft gear 12 to be tested, select the corresponding conical expansion sleeve 301 and arc-shaped limiting block 304, and install them onto the expansion sleeve support seat 4. Rotate the drive handle 403 to adjust the position of the expansion sleeve support seat 4, and then tighten the clamping device to lock the position, or adjust the second drive cylinder 10 to leave sufficient clamping space between the small end of the conical expansion sleeve 301 and the small end of the conical spindle 5. Adjust the steel ball 107 of the display component 1 to be directly above the top surface of the half-shaft gear 12 gear ring, and preload the dial indicator 103 by about 0.2 mm.

[0039] Insert the half-shaft gear 12 into the small end of the tapered expansion sleeve 301 until the internal spline of the gear contacts the arc-shaped limiting block 304. Slightly rotate the half-shaft gear 12 to make the arc-shaped limiting block 304 engage with the internal spline. Activate the second drive cylinder 10 to push the main shaft support 9 to the right, so that the small end of the tapered main shaft 5 is inserted into the inner hole of the tapered expansion sleeve 301. When the floating ring disk 208 contacts the end face of the half-shaft gear 12, the push spring 202 is compressed, providing a constant axial preload.

[0040] At this point, if there is a perpendicularity error on the end face of the half-shaft gear 12, the floating ring disk 208 will adaptively tilt through the spherical pair, so that the end face of the gear is completely in contact with the floating ring disk 208, avoiding gear deformation caused by forced flattening. Continue to push the tapered spindle 5 to the right, and the tapered surface of the tapered spindle 5 interacts with the inner tapered surface of the tapered expansion sleeve 301, causing the tapered expansion sleeve 301 to expand radially evenly, forming a clearance-free interference fit with the inner hole of the half-shaft gear 12.

[0041] When the tapered spindle 5 moves to the predetermined position (based on feedback from the pressure sensor of the second drive cylinder 10), the first drive cylinder 7 is activated, pushing the clamping cone head 601 to move to the left and into the positioning socket at the right end of the tapered spindle 5, completing the entire clamping process. At this time, under the action of the compression spring 303, the arc-shaped limiting block 304 is always pressed against the right end face of the half-shaft gear 12, while the left end face is completely fitted with the tapered expansion sleeve 301 through the inner wall to form a positioning, thereby achieving reliable axial positioning.

[0042] Gently turn the handle 11 to drive the conical main shaft 5, the conical expansion sleeve 301 (which rotates together with the main shaft 5 through friction) and the half-shaft gear 12 to rotate synchronously for one revolution. After confirming that there is no jamming or looseness, zero the dial indicator 103. Slowly turn the handle 11 to rotate the half-shaft gear 12 360°, and record the maximum and minimum readings of the dial indicator 103. The difference between the two is the radial runout of the gear ring of the half-shaft gear 12.

[0043] After the test is completed, the first drive cylinder 7 and the second drive cylinder 10 are started in reverse, causing the clamping cone head 601 and the conical spindle 5 to move to the right and left respectively. After the conical spindle 5 moves to the left, the conical expansion sleeve 301 automatically contracts under its own elasticity, disengaging from the inner hole of the half-shaft gear 12. At this time, the half-shaft gear 12 can be directly removed from the small end of the conical expansion sleeve 301, completing one test cycle.
